I have had a starting issue ever since I had an Ultima 3.25" belt drive installed. I have a 113" Ultima and Ultima starter. When I tried to start the bike, I just hear a loud winding noise and grinding. So I know the jack shaft is not engaging with the starter gear ring on the belt drive. For me to get it engaged all the way. I will have to hit the starter button a bunch of times. Another way is when I push in the solenoid button, i will roll the bike fwd and rev a little for it to engage. Another thing is, when I loosen the the starter gear cover a little, it starts up just fine.

I ordered a new jack shaft from Jireh, the one that they say goes with the belt drive. It is the same jack shaft that I already have on the starter. The jack shaft has 9 teeth. Has anyone else have had this problem before? Maybe a 10 tooth jack shaft? When I had my primary on, it would start every time, just fine. Any help would be appreciated. Thanks

 

Check the air gap from the pinion to the ring gear and report back.

 

BAGGERDSM, this is a dumb question. As in pinion, what part are you talking about? I am just starting out with working on bikes.

 

The below link is a short vid of what the issue looks like. I can't try starting the bike, due to the oil tank and battery not being installed. When the shaft is able to engage, it gets stuck. When I manually push it back in. The gear to the jack shaft rotates back.
